According to Compete.com, Bing was able to amass 49.57 million
unique visitors in its first month as Microsoft’s official search
engine. Bing’s traffic trumps that of Digg (38.96 million)
Twitter (23 million), and CNN (28.54 million). We want to stress
that this focuses on U.S. visitors, since Compete does not track
international visits.

We'd also note that Bing already had a huge firehose of visitors
via Live.com, and that Compete's unique visitors are hardly the
best way to measure Bing's effectiveness -- other metrics like
comScore's search reports will be more telling.

Moreover, while Microsoft can easily juice Bing's traffic via its
advertising spree, it'll be much more interesting to see how Bing
is doing later this year.
